$\begin{matrix}\left(1\right)\left(-3\right)=-3\\ \left(1\right)+\left(-3\right)=-2\end{matrix}$
Learn how to solve problems step by step online. Find the limit (x)->(3)lim((x^2-2x+-3)/(x-3)). Factor the trinomial x^2-2x-3 finding two numbers that multiply to form -3 and added form -2. Thus. Simplifying. Evaluate the limit \lim_{x\to3}\left(x+1\right) by replacing all occurrences of x by 3.
